This invention relates to new and useful improvements in dispensingmachines.

One object of the invention is to provide an improved dispensing machinefor vending bottled beverages or other articles, being of rugged,compact construction and having positive substantially fool-proofoperating means.

Another object of the invention is to provide an improved dispensingmachine having one or more rotatable reels or racks for receiving andstoring a plurality of articles to be vended, there being means forcontrolling the rotation of each reel whereby the same movesintermittently or step by' step to deliver or discharge the articlesindividually.

A particular object of the invention is to provide an improveddispensing machine, of the character described, wherein the reel isrotated by the gravity of the articles stored therein and the dischargeof said articles from said reel is controlled by means associatedtherewith and arranged in such manner as to permit the delivery of onlya single article upon each operation of the reel.

An important object of the invention is to provide an improveddispensing machine, of the character described, wherein the means forcontrolling the operation of the reel is rendered inoperative upon thedischarge of the last article from said reel whereby the reel ispositively locked against movement.

Another object of the invention is to provide an improved dispensingmachine, of the character described, wherein the means for controllingthe operation of the reel may be operatively disconnected therefrom topermit freewheeling of said reel and facilitate refilling thereof, therebeing means associated with the reel adapted to be swung to a closedposition so as to prevent the discharge of articles from said reelduring refilling of the same.

A further object of the invention is to provide an improved dispensingmachine which includes a rotatable rack having individual compartmentsformed by longitudinal partitions having transverse projections forreceiving articles therebetween, the partitions being disposed at theouter peripheral portion of the rack and terminating short of the hubthereof so as to lighten the weight of said rack and permit closespacing of the articles.

A construction designed to carry out the invention will be hereinafterdescribed together with other features of the invention.

In the drawings, the numeral Ill designates a dispensing machine whichincludes an'enclosed, upright housing or casing l l of rectangular formand having suitably insulated walls I'Z. An access door [3 is providedin one side wall ofthe casing I I and is adapted to be locked in theusual manner. Below the door 13, a horizontal partition It extendsacross the interior of the casing so as to provide an upper chamber 15and a lower chamber t6 (Figs. 4 and 5). The upper chamber I5 functionsas a cooling chamber and has cooling coils l'l therein extending tosuitable refrigerating means (not shown) in the lower chamber IE5. Asupport or frame It is mounted in the chamber It for rotatablysupporting a reel or rack is between the coils ll. As will behereinafter more fully explained, the reel 19 has a plurality oflongitudinal compartments 25 for receiving and storing articles A to bevended which have been illustrated as bottled beverages. For retainingthe articles in the compartments 2!! upon rotation of the reel, asubstantially semicircular fence or guard member 2| is supported by theframe l8 below and in close proximity or concentric relation to thelower peripheral portion or half of said reel. The fence 2| includes apair of arcuate sections 22 and 23 having complementary curved gates 24and 25 pivotally connected to their respective inner end portions.

'The gate '24 functions as a closuremember and is normally swungdownwardl to permit the discharge of articles from the reel to aninclined trough or chute 26 disposed therebelow, such discharge beingcontrolled by the gate 25. A discharge opening 21 is formed in thefrontside wall of the casing for receiving the lower projecting end ofthe chute 26 which has its outer end closed by a retaining wall or stop28. Rotation of the reel is controlled by an .operating mechanism 29having its actuating rod or handle 30 extending through the casing frontwall. A cap remover and receptacle 3|, of usual construction, maybemounted on the casing front wall.

The frame I8 is of skeleton construction and includes upright cornersupport or legs 32 connected by suitable cross bars 33 extendinghorizontal-ly between the ends and the intermediate portions of the legsand disposed at right angles to each other, whereby the interior of saidframe is open and unobstructed. For rotatably supporting the rack orreel l9, a shaft 34 extends axially through said reel and has itsprojecting ends engaging in suitable brackets 35 carried by an opposedpair of the top cross bars 33. Thus, substantially one-half of the reelis positioned within the frame. The reel includes a pair of circular endplates 36 connected-by an axial, cylindrical hub 37 which surrounds theshaft 34 (Fig. 3). A plurality of equally-spaced, longitudinal membersor partitions 38 extend between and connect the peripheral portions ofthe end plates 36 and terminate considerably short of the hub 31. Thepartitions 38 are preferably triangular or wedge-shaped in crosssection,being radically disposed and having their apices directed inwardly (Fig..5). A plurality of transverse ribs or projections 39 are formed on thetapered sides of the partitions in equally-spaced relation with the ribof each partition being alined with the complementary ribs of the otherpartitions :to provide alined divisions. It is noted that thecompartments 20 are formed by the coaction of adjacent partitions andthat said compartments are disposed in parallel relation, whereby thearticles in the compartments are arranged in longitudinal andcircumferential rows. The spacing of said partitions and ribs is inaccordance with the size of the article A, whereby said compartments areof sufiicient area to accommodate said articles. As shown in Fig. 5, theinner ends of the articles engage the hub :36 which forms a bottom foreach compartment. When the articles being vended are in the form ofbottles, the reduced ends of the bottles are disposed in close proximityto one another and their enlarged bases are properly positioned by thewedge-shaped partitions. Manifestly, the diameter of the hub as well asthe shape and spacing of the partitions and their ribs may be varied toconform to the character of the articles to be vended.

As set forth hereinbefore, the guard or fence 2| encircles the lowercircumferential portion or half of the reel Hi to retain the articles inthe compartments 2!). The arcuate fence sections 22 and 23 arepreferably formed Of a plurality of curved rods or bars 46 which areconnected to and extend from immediately above the top cross bars 33 toa point adjacent one of the intermediate cross bars of the frame 18.Suitable transverse bars 4i connect the rods 46 to each other and anglebrackets 42 secure the ends of the bars to the aforesaid intermediatecross bar of the frame (Fig. 4). One Of the rods 40 is provided for eachcircumferential row of compartments and is preferably disposedintermediate the respective ribs of said compartments to support andprevent the articles from escaping therefrom. As shown in Fig. 5, thebases or outer ends of the articles engage and ride upon the rods. Thecomplementary gates 24 and form continuations of their respective fencesections and have arcuate fingers or rods 43 and d4 pivotally connectedto the lower ends of the rods of said fence sections (Fig. 4). Atransverse bar 45, of lesslength than the 'fence'bars 4 l, is welded orotherwise secured to the rods 44 of the gate 25, while the gate 24 hasits rods connected by a pair of similar bars 46. When the gate 24 isswung upwardly, the free ends of its rods 43 are adapted to be disposedin substantially abutting relation to the adjacent ends of the gate rods44 so as to prevent articles from being discharged into the chute 26. Inorder to control the dis charge of the articles and provide a singledelivery upon each operation Of the reel, the rods 44 are ofprogressively increasing length and the complementary rods 42 are ofprogressively decreasing length from the front to the back of the gates.Due to the stepped relation of the rods 24, one division of one of thereel compartments is moved beyond the end of its respective rod uponeach actuation of the reel to discharge a single article. Thus, articlesin adjacent divisions of the same compartment are dischargedindividually upon the intermittent operation of the reel until saidcompartment is emptied. At this point, the first division of theadjacent clockwise compartment is in such position that the articletherein is discharged upon the next operation of the reel.

Downward movement of the gate 25, which functions as a discharge controlmember, is limited by the engagement of its rods 44 with the I uppersurface of the chute 2B. The latter is inclined upwardly from thedischarge opening 21 and extends at angle to the axis of the reel I9 soas to underlie the opening formed by the gates. Although of any suitableconstruction, the chute is substantially semicircular in cross sectionand has its upper end suspended from the frame l2. A depending plate 41,having a circular opening 48, supports the discharge end of the chute.Swinging of the gate or closure member 24 is controlled by a lever 49which is pivotally connected to a link or bar 50 carried by the forwardend of said gate. The lever 49 extends transversely beneath the reel andabove the discharge end of the chute and terminates adjacent the doorI3, as shown in Figs. 3, 4 and 5. A notch 49 is formed in the outer endof the lever for engaging an angle bracket 5| secured to one of theframe legs 52 to fasten the closure member in its lowered or openposition (Fig. 9). Upon opening the door 13 and moving the leveroutwardly, the closure member is swung upwardly to its closed position.The lever carries a curved deflector plate 52 which extends parallel toand adjacent the lower end of the chute for directing articlesdischarged from the reel into said chute.

The rack or reel I9 is adapted to be rotated by gravity or the weight.of the articles stored therein and the compartments and partitions 38are omitted from one portion 53 of said reel (Figs. 2 and 5) to insuresuch rotation. Since the reel rotates in a counter-clockwise direction(Fig. 5), the void portion 53 is positioned counterclockwise or to theright of the gate or control member prior to placing the machine II] inoperation after each refilling of said reel. The reel is counterbalancedby suitable weights (not shown) so that the same may be readily turnedabout its axis when empty. As has been explained, rotation of the reelis controlled by the operating mechanism 29 which includes a ratchetwheel assembly 54 mounted upon the frame [8 adjacent the gate 25. Atoothed disk or circular plate 55 is carried by one of the end plates 36for coacting with the ratchet wheel assembly 54 and the peripheralradial teeth 56 thereof are preferably rounded or curved.

As is most clearly shown in Figs. 9 and 10, the ratchet wheel assemblyincludes an axial shaft 51 extending parallel to the reel shaft 34 andhaving one end journaled in an opening 58 formed in an upright brace 59of the frame. The opposite end of the shaft 51 is slidably mounted in abearing 60 which is supported by a bar 6| extending transversely of theframe and secured to the cross bars 33 thereof. A small spool 62 iscarried by the shaft between the frame brace 59 and bearing 60 and has aplurality of equallyspaced, longitudinal rods or pins 63 atits periph- 1eral portion for engaging the teeth 56 of the reel disk 55. The spacingof the teeth and pins is such that a slight rotation of the reel ispermitted upon each engagement of one of said rods with one of saidteeth and this rotation is sufficient to move one of the articles A pastits respective finger 44 of the gate 25. A ratchet Wheel or disk 64,having angular, clockwise-directed teeth 65, is mounted on the shaft 5!at one end of the spool and is adapted to coact with a pair ofpivotally-mounted pawls 66 and 61 (Figs. 7 and 8) for controlling therotation of said spool and the reel. The ratchet wheel 64 is maintainedin coacting relation to the pawls 66 and 61 by a leaf spring 68 securedto the frame brace 59 in overlying relation to the end of the spoolshaft which projects through the opening 58.

For moving the ratchet wheel out of engage- .ment with the pawls topermit free-wheeling of collars or tubular posts '15 and 16 which arerotatably mounted upon an inclined support or base Tl secured to one ofthe frame cross bars 33. A pair of linksl'B and 19 are connected to theposts 15 and 15 and are pivotally connected to each other by a cross arm8!], wherebyreciprocal movement of the links causes oscillation of bothof said posts and their pawls. The latter are in the form of flat armsor blades Bl which project toward each other in overlapping,vertically-spaced relation, being disposed between the posts andoscillating in opposite directions upon turning of said posts. As ShOWnby the numeral 82, the leading edges of the blades 8| are bevelled forcoacting with the inclined surfaces of the ratchet teeth 65. Therelative positions of the pawls and ratchet teeth are best illustratedin Figs. 11, 12 and 13. In Figs. 8 and 11, the pawls are shown in theirnormal positions prior to actuation of the control mechanism 29. InFigs. 7 and 12, the pawls are shown in an intermediate or half-wayposition with the upper pawl 16 being retracted out of engagement withone tooth and the lower pawl Tl engaging the adjacent counter-clockwisetooth prior to engagement of said upper pawl with said latter tooth. Thelinks 18 and 19 have been reciprocated to the left so as to turn theposts '15 and 16 in a counter-clockwise direction, while the spool 62.

and its pins 63 have revolved in a similar direction to permit rotationof the reel H3 in an opposite direction. Reverse reciprocation of thelinks causes reverse oscillation of the posts and their pawls, wherebythe pawl ll moves out of engagement with the adjacent tooth and the pawl16 moves into engagement therewith. :As shown in Fig. 13, the upper pawlmoves into the path of the tooth prior to the disengagement of the lowerpawl therefrom. After full reciprocation of the links and oscillation ofthe pawls, the

the reel when it is desired to refill the same, a

bell-crank 69 is pivotally mounted upon the bar 6| and has an upstandingpin 10 engaging the end of the spool shaft which is slidably mounted inthe bearing 60. A lever H has one end connected to the free end of thebellcrank 69 and its opposite end to a link 12 which is pivotallysupported by the bar 6|. The link 12 depends below the bar and has atransverse pin 13 adapted to be engaged by a lug or projection 14carried by the gate lever 49. Upon outward movement of the gate lever,its lug l4 strikes the pin 13 so as to swing the link 12 in a clockwisedirection and move the lever H longitudinally to the right, therebypivoting the bell-crank 69 in counterclockwise direction. Due to theengagement of the pin 10 with the shaft end, said shaft is slidlongitudinally to the left so as to move the ratchet wheel out ofcoacting relation with the pawls. The spool pins 63 are of sufficientlength to permit this longitudinal movement and remain in ratchet wheeland spool revolve the distance be tween adjacent ratchet teeth to permita similar rotation of the reel. This amount of movement is sufiicient tomove one of the articles A past its respective gate finger M and permitthe discharge of said article into the chute 26. Due to the bevellededges 82 of the pawl blades 8!, said blades ride along the inclinedsurfaces of the ratchet teeth and force rotation of the ratchet wheel inthe event the same sticks due to freezing.

The link 18 is elongated and is connected to one end of a traverse lever83 which has its opposite end fastened to one leg of a pivoted hanger 84which depends from one of the frame cross bars 33 (Fig. '7). Anelongated link or bar 85 connects the other leg of the hanger 84 to theoperating plunger 39, whereby reciprocation of said plunger istransmitted to the link 18 by swinging of the hanger and the lever 83.If desired, a plurality of openings 86 may be formed in each hanger legto permit adjustment of the connections between the above elements. Inorder to lock the control mechanism and render the same inoperative, asmall plate or flange 81 projects laterally from the bar 85 in closeproximny-tman-angular arm; 88 carried by: the .gate 25. .Thearm 881s;counterbalanced by a suitable weight 189 -sogas;to.;swing downwardlyinto the pathof the flangei-Bl to prevent movementof the-bar =85 when noarticle is resting upon. the fingerswflof the gate. However,:this weightis insufficient .to lift the gate .when .anarticle is resting thereupon.Upwardswinging of the gate islimited by an angle bracket ;90 .mounted'ontheframe and overlyingia cross barv 9 [projecting laterally from saidgate (Fig. 4). For. locking the reel l9xagainst rotation, a lock bolt orplunger 921s slidably mounted uponthe uppermost frame CIOSSYqbBJ 33adjacent the door 13 in-a-suitable housing-93 and extends-at. a rightangle to the reel disk 55 forengaging the notched'per-iphery thereof..The housing ,93 has .an angular or .L- shaped slot 94 for receiving .ahandle 95 carried by: the'plunger 92 and preventing engagement of saidplunger with the disk teeth 66 except-when the-door isopen (Fig; 14)

.In placing. the herein: described machine in operation, thedoor l3.isopened and the lever.-49 pulled outwardly soas to swing the gate-orclosure member 24' :upwardlyanddispose its fingers 43 into underlyingrelation to the circumferential rows of. the. reel compartmentslfl. :Atthe same time, the lug'Mof the lever strikes thepin 13 of the'link l2to'reciprocate the lever. 7i and swing the when-crank 69 with its pin soas to slide 1211821813001 shaft. 51 longitudinally for disengagingits:ratchet wheel fidrfrom the pawls 66 and 61. The reel 19 may now bereadilyrotated by hand and its compartments filled with;bottles or otherarticles to be'rvended. During'the filling step, the. locki'plungerill-may be engagedwiththe notched peripheryof the reel disk 55 .wheneverdesired to. prevent rotation ofthe reel. As soon as articles, rest uponthe fingers; Mofrthe gate 25,

(Fig..5),the"arm188 is swunguupwardly out of the path-of the flange 87ofthe bar'85 to unlock the control-mechanism 29 (Fig. 7).

When the'fillingofr the reel is completed, "the same :is-rotated so astodispose its void 53 above the gate 24 with :the. adjacent clockwisecompartmentiZUabove' the'ends of the :fingers'M of the gater25-as shownin Fig. 5. 'The lever-49 is thenupushed. inwardly to swing the gate 24downwardly to itsopenopositionland. move the lug .14" out of. engagementwith the link pin 13, wherebythe spring 68 slides the spool shaftlongitudinally soas to dispose the ratchet wheel in coactingrelation tothe pawls 66 and '61. During re-engagementof the ratchet wheel with thepawlsfthe lock plunger'92 is engaged with the teeth-2165.0f the-diskreel to maintain said reel in position. The machine is now ready foroperation. Although not illustrated in detail, actuation of theoperating plunger 30 is controlled by a coin-device C of the usualconstruction. As has beendescribed, inwardrmovement of the plunger istransmittedby the-barn85, hanger .84 and-lever. 83 to the. linkx'lB.and'from said link to the-link .19. by the; cross-arm. .80. was tooscillate the posts' and .16 and their pawls 66 and from the-positionshown:in Figs.:8gand llwto the'position shownqinFigs. 7 and .12.
